Application filed March r24, 192'?. Serial N'o. 177,868.

proceeds, the invention` resides inthe combination and arrangement of parts and in the details ofconstruction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention hereinafter disclosed can be made within the scope of what is claimedwithout departing from the spirit of the invention. y

In the drawing wherein like numerals of reference designate corresponding yparts throughout the several views Figure 1 is a side elevational ,view of a potato peeler constructed in accordance with the invention.

Figure 2 is a vertical `sectional view thereof. Y

Figure 3 is a top plan view of the device with the cover removed therefrom. p

vFigure 1 is an enlarged sectional view on line IV-[V, Figure 1. V f Figure 5 is a side elevational view of the grater cylinder.

Referring in detail to the drawing 1` def notes a vertically disposed, cylindrical casin includinga bottom 2 and provided with. a removable cover 3. The casing 1 is supported on the legs 4, which are fixed thereto in any suitable manner.

The cover 3 is provided with a. hinged door 5 which embodies a panel of glass or other transparent material to enable the operator to view the peeling operationin the interior of the casing 1 without necessitating the removal of the cover 3 from the latter. The cover 3 is further provided with a hose con nection 6 which connects with a hose 7 adapted for attachment to a water faucet supplying a continuous flow of,` required water through the casing 1 during the peeling operation. The water isdischarged from the casing 1 through a drain pipe 8 fixed in the casing bottom 2. v p Y i A circular supporting disk 9 is rotatably mountedin the casing 1 adjacent to thebottom 2 of the latter. The supporting disk 9 is detachably supportedon a. centrally vdisposed perpendicularly depending spindle 10 to rotate with the latter. The spindle 10 is suitably journaled for rotation in the Vbearing 11.. The latter is fixed in the diametric center of the casing bottom 2. Y

The lowerend of the spindle 10 projects through the bearing 11 and carries a small bevel gear 12. The latter meshes with a coinparativeiy large driving gear 13, whichwis fixed on the inner end of a horizontally disposed `drive shaft 14. The -drivesliaft 14 is journaled for rotation in suitable bearing brackets 15 which are fixedto the underside of the casing bottom 2. The outer end of the' drive shaft 11i is provided with an operating handle 16 for manually operating the device. 1f theV device is lto be power driven the handle 1S isreplaced with a pulley or gear adapted for4 connection with asuitable power transmission element. The relative rate of the associated `gears 12 and 13 is such as toiimpart the proper operating rotation to the supporting disk'9 to 'bestmeet conditions.

A casing liner or grater cylinder 17 is removably mounted in the casing 1. The grater cylinder 17 is .disposed vertically, and is slightly spaced from the inner periphery of the casingl. yThe grater `cylinder 17 has ,openv ends and is formed with a vertically disi posed opening 18 which extends throughout` thelength thereof. The width. of the opening 18 is commensurate to the width of the dooil n opening 19, which is formed in the side wall of the casing 1. When the grater cylinder is mounted in the casing 1, the openin 13 .of-the former registers with y the doorv opening 19 of the latter. y y The upper end of the grater cylinder 17 is re-enforced-by an annular wire ring' 20, which is disposed on the outer side ofthe gratci cylinder 17 and which is maintained in position by overlapping the saine with the inarginal top edge of the grater cylinder .17.

The lowerv end of the grater cylinder 17 is provided with asimilarly disposed resilient re-enforcing rod 21. -Thelatter, however, does not extend across the vertically disposed opening 18. y f The casing 1 is formed with Va plurality of regularlyV spaced, vertically extendingand inwardly impressed ribs 22, which have their ends disposed adjacent torespective ends-of .the casing 1. When the grater cylinder 17 is mounted inthe casing 1, the ribs 22 extend between and engage the re-enforced ends of vposed .indentations, which. are positioned the casing 1 and prevent the vertical movement of the lgrat-er cylinder17 in the latter during the operation of the device.

As the resilient re-eniorcing rod 21 does not extend across the lower end ot the spring 18, ot the grating cylinder 17, the lower end ot' the latter can be resiliently compressed to permit ot' its passage over the inwardly disposed casing ribs 22. The return ot the lovver end of the grater cylinder 17 to its normal position, after being mounted in the casing 1, as above described will secure the grater cylinder against vertical movement in the 'asing 1.

The grater cylinder 17 is constructed from sheet metal and .has its entire Wall arca covered With a'inultiplicity ot inwardly disin close proximity to each other. These indentations perliorate the cylinder 17 and term rough, sha-rp, grating burrs 23 on the inner side ot the latter.

Similarly constructed and arranged grating burrs 24 are Ji'ornied on the top tace ot the circular grater disk 25. The latter is d-etachably mounted and secured on the top of supporting disk 9 by means ot screws 26, or in any other suitable manner, to permit and facilitate the removal ot the grater disk 25 trom the supporting disk 9 for the purposes oiQ cleaning or replacement.

The casing side ivall opening 19 is provided with a hinged side door 27. The latter is provided with a latch 28 for securing the same in the closed position. The inside ot the side door 27 carries a fixed grater plate 29 covered With grating burrs 30, which are identical to those formed on the grater cylinder 17 and on the grater disk 25.

The grater plate 29 is inset, or curved m- Wardly to extend into the casing 1 when the side door 27 is in the closed position. One side edge 31 ol the gratei." plate 29 is disposed on the saine cir-cumterentia-l plane as the Wall of the grater plate 29, which is disposed 'for-y wardly, relatively to the counter clockwise direction oi rotation ot the supporting disk 9 and ot the grater disk 25 secured thereto, extends for a considerable distance into the casing 1, as clearly shown in Figure ll.

A vertically extending flange 33 is fixed to each marginal side edge of the side door 27 on the inner side of the latter. rlihe flange 33 engages respective sideV edges oi4l the. grater cylinder opening 18 when the side door 27 is in the closed position, and prevent circumferential movement of the grater cylinder 17 during the operation or` the device.

The supporting' disk 9 is -t'ormed with a plurality or enlarged openings 341 Which provide a passagetor removed peelings as the latter are Washed through the perforated burrs 211 in the grater disk 25 bythe action ot the Water during the peeling operation.

The supporting disk 9 together vv-itlr the horizontally disposed, vertically groter disk 25 provided thereon constitute the rotor or". the device, and are i'orm'ed with a pair of spaced apertures 35, which are adapted tor engagement by a detachable, resilient handle 36 to facilitate the release ot the rotor trom its attachment with the spin dle 10 and its removal and replacement from and to the casing 1, for cleaning purposes.

1n practice, the operation ot the apparatus is as iolloivs: A number of potatoes are placed in casing 1 on the grater disk 25 and in the gratter cylinder 17. A contiimouusv iloiv ot' water is passed through the casing 1. The Water enters the casing 1 through the hose 7, attached in the cover 3, and is dis# charged through the drain pipe 8, in the casing bottom 2.

rllhe rotation ot the rotor is very rapid and the centrifugal force created by such-rapid rotation Will cause the potatoes to be whirled and rolled in all directions with considerable torce against the burred inner side oli-the grater cylinder 17 and on the burred top face ot the grater disk 25. When passing along the inset grater plate 29, the lat-ter Will tumble the potatoes to vary their positions so all portions thereof must inevitably contact with the burred sides or" the grater cylinder 17, disk 25, and plate 29.

The grating action of the grater `elements 17, 25 and 29 upon the rapidly moving `potatoes, Will remove all peelings from thelatter in a most thorough, efficient and economical manner.

The flow of Water through the casing 1 Will facilitate and expedite the peeling operation, as the Water will carry away the removed peelings through the perforated burrs in which such removed peeling would normally tend to lodge.

By opening the casing side door 27 and revolving the rotor, the potatoes may beremoved from the casing through the said side door 27 bythe centrifugal action imparted to the potatoes by the revolving rotor. Such ren'ioval ot' the potatoes -t'rom the casingfl eliminates the necessity of removing them by hand through the open top ol' the casing 1.
